A few weeks ago, I quoted from an editorial that was in the Salt Lake Tribune (unfortunately, my link to the article doesn't work anymore). The author had an interesting prediction for what might happen if Mary Landrieu were re-elected to the Senate from Louisiana, which she was on Saturday.
Prediction: There is a 50-50 chance that McCain and Chaffee will switch parties and a similar chance that McCain will become the Democratic standard bearer in 2004.
It will be very interesting if this is correct, since it would give the Senate back to the Democrats again.
